Dave Lee of GoBackpacking.com recently saved $30,000, quit his full-time job, and hopped on a plane to travel the world for a year or more. “While I’m not going to be the lightest guy on the road, weighing in at a total of just 20lbs fully packed, minus the clothes on my back,” he wrote in an email late last month, just 48 hours before departure. “It’s hard to avoid carrying technology now that it’s so small, light, and inexpensive, though I know I could drop a few pounds if I ditched a bit of it.” So, Dave, what’s in your pack?
